A) 38*(1-20%)*(1-10%)=27.36
b)38*(1-30%)=26.6
c)Because in question one when you take off the 10% it is 10% of the already off price but when you take off 30% it is taking off from the original price
Answer:
x=1
Step-by-step explanation:
8+2x-7x=5(x-3)-2(6x-8)
8+2x+7x=5x-15-12x+16
8+15-16=5x-12x-3x-7x
23-16=-7x-3x-7x
17=-17x
x=1
Answer:
53.44 cubic meters
Step-by-step explanation:
A cylindrical oil drum is 2.1 meters high and has a radius of 0.9 meters. How many cubic meters of oil can the drum hold? (volume)
Volume of a cylinder = π × r² × h
r = 0.9 meters
h = 2.1 meters
= π × (0.9m)² × 2.1m
= 53.44 cubic meters
Therefore, the volume of the cylindrical oil drum = 53.44 cubic meters
Can you rewrite the equation? It doesn’t make sense
